To all whom it may concern:

Be it known that we, Anorsrns C. Lirrnnr and JOHN A. Srmro, citizens ofthe United States, residing, respectively, .in

Kenosha and Chicago, in the counties of Kenosha( 1ook and States of W'isconsin- Illinois, have invented a new and uselul lmprovement in Radiator =Caps, of which the following is a specification.

Our invention relates to radiator caps for automobiles or the like and to an improved method of assembling the parts thereof, and has for a principal object the reduction of the cost of both the parts andthe manufacturing operations involved.

The general. construction of radiator caps, of the character with which this invention is concerned, involves the use of an internal collar adapted to be threaded, or otherwise secured to the radiator neck, and an external collar adapted to fit around the internal collar and to be locked thereto, in such manner that said internal collar-cannot be removed from the radiator neck by force applied to the external collar. The present invention contemplates the provision of an internal collar of cheaper material than has been usable with the type of caps heretofore employed, this material also lending itself to a method or": assembly which further reduces the cost otmanufacture. A further object isnthe PIOVJSIOIL of an improved ratchet lock/between the collars of a radiator cap oft this character, this being for the purpose of locking the collars together when the outer collar is turned in one direction to permit the cap to be screwed upbn the radiator neck, while penmitting the outer collar to be relatively turned in the opposite direction to prevent removal of the after it is positioned.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following descript-ion, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

Referring to the drawings,

Fig. 2 is a horizontal section taken substantially on the line 2-2 of Fig. 1.; Y

Fig. 3 is a similar section taken substantially on the line 3-3 in Fig. 1;

Fig. 4C is a detail perspective view of the ratchet member which is disposed between the collars of the cap;

Fig. 5 is a vertical section of the outerand inner collars of the cap positioned upon the dies by which they are assembled, and;

Fig. 6 is a top plan view or" the dies em? ployed in carrying out the method of our invention.

Upon the'drawings, We have shown both a radiator cap assembly constructed in ac cordance with our invention, and also the apparatus by which the method invention is carried out.

Describing first the assembled cap, the reference character 21 indicates an outer collar which fits around and is secured to an inner collar 22, which latter is provided with threads 23 at its lower end and adapted to be screwed into a-radiator neck 2 upstanding from an automobile radiator casing' .25. The collar 21 is provided with laterally extending arms 26, the ends of which are enlarged and synnnetrically formed, as indicated at 27, to provide a pleasing and ornamental appearance. At the front of said collar, there is formed an integral lug, or

projection, 28, which, in the present inv stance. is of keystone form and is adapted to receive a suitable inscription, or deeoraf tron, whicln if desired, may be provided on a separate piece secured to the front of said projection. A pivoted'closure 29 is provided to close an opening 31 in the top of the collar member 21, said closure being" adapted to have a motometer 32, or like instruniet, permanently secured thereto. A thumbscrew 33 is employed to tighten said closure 29 upon the collar, to firmly engage a gasket which may be positioned in a space J4 be tween an inwardly extending flange 35 on' the inner collar and a corresponding flange on the outer collar, said closure being pro-- vided at the bottom with a beveled gasket-:

engaging surface 37, which may be forced,v

" tightly against the gasket by means of the thumb-screw 33. Said collar 21 is provided with an interior circumferential groove, oi"

recoss, 38 adapted to receive projectionsfifi formed in the body of the collar 22, these the oted on said external collar adapted to have a motometer or the like permanently secured thereto.

a. In a radiator cap for automobiles or the like, the combination of a sheet metal internal collar having means for attachment to a radiator neck, an integral projection on the exterior of said collar, an external collar adapted to fit about said internal collar and having a groove adapted to receive said projection to lock the collars together against theft, and a pivoted closure on said external collar adapted to have a motometer or the like permanently secured thereto.

5. In a radiator cap for automobiles or the like, the combination of a sheet metal internal collar having means for attachment to a radiator neck, an integral projection on the exterior of said collar, an external collar adapted to fit about saidinternal collar and having a groove adapted to receive said projection to lock the collars together against theft, and means rest-raining rotation of the outer collar in one direction While permitting it in the other.

6. In a radiator cap for automobiles or the like, the combination of an internal collar having an opening therethrough and having means for attachment to a radiator neck, an external collar fitting around said internal collar, a pivoted closure for said external collar adapted to have a motometer or the like permanently secured thereto, said collars being assembled in interlocked relationship to prevent separation thereof, and means having co-extending sides of substantially U-shaped configuration adapted to be laid in a recess in said internal collar and to collar, a pivoted closure for said externalcollar adapted to have a inotometer or the like permanently secured thereto, said collars being assembled in interlocked relationship to prevent separation thereof, and means adapted to be laid in a recess in said internal collar and to engage in a recess on the external collar whereby to prevent relative rotation of the external collar in one direction, though permitting it in the other, said means comprising va spring clip having a backing portion adapted to be seated in said recess in the internal collar and a resilient ratchet forming portion bent over upon said backing portion and adapted to project from the surface of the internal collar to engage in a ratchet recess on the external collar when the latter is rotated in direction to position the cap upon the radiator.
